WASHING-MACHINE.

-SPECIPICATION forming part of Letters Patent'No.357,236, dated February 8, 1887.

Application filed June 1'7, 1886. Serial No. 205,399. (No model.)

To all whom it may concern:

Be it known that we, FRIEDRICH ScHUMPE and FREDRIOK MOLLENKAMP, both citizens of the UnitedStates, residing at Cincinnati, in the county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Washing-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to those washing-machines whichinclude' a tub having a hinged lid .that covers the same, a vibrating rubber fitted within said tub, an operating-lever traversing a longitudinal slot of said lid, and a provision for raising the rubber out of the tub and temporarily coupling it to the lid preparatory to opening the latter; and the first part of our improvements comprises a novel combination of devices whereby a yielding pressure is imparted to the rubber, as hereinafter described and claimed. To accomplish this result the aforesaid rubber is provided with a pairrof journals that traverse vertical guides in the opposite sides of the tub, and said journals are forced downwardly by push-pieces fitted within vertical slots or grooves of the lid, the latter being hinged to one end of the tub. These push-pieces have lateral extensions to which the desired yielding pressure is imparted, either by weights or springs, as

hereinafter more fully described.

The second part of our improvements consists in providing the operating-lever with a transverse slot, through which a key or pin is passedand brought to bear against a pair of stopswhen the rubber is elevated, by which arrangement .the latter is temporarily coupled to the lid preparatory to opening the same, either for filling the tub or removing the washed clothes, as hereinafter more fully dcscribed and claimed.

In the'annexed drawings, Figure 1 is a side elevation of our washing-machine, the lid of the same being closed and the rubber beingin its normal position. Fig. 2 is a transverse section of the machine taken in the plane of the push-pieces, therubber being elevated and coupled to the lid. j Fig. 3 is a side elevation showing the lid and its coupled rubber thrown open. Fig. 4:.is an enlarged vertical section of a portion of the machine taken in the plane of one of the push-pieces. Fig. 5

is an enlarged plan showing the key inserted in the slot of the rubber-lever, thelatter being.

sectioned.

A represents an ordinary tub mounted upon legs a, and having a concave bottom, B, provided with transverse ribs 'or corrugations b, as seen in Fig. 2.

O G are metallic guides let into the opposite sides of the tub, and c c are stiffening blocks or plates applied to said sides and adapted to cover the outer edges of said guides, which latter receive the journals or pivots d d of the vibrating rubber D, the under or effective surface thereof being convex and provided with transverse ribs or corrugations E. Rigidly attached to this rubber is a lever, F, the up per or exposed end of which is coupled at f to one end of a connecting-rod, G. The opposite end of this rod is j ointed at g to an operating-handle, H, and the latter is fulcrumed at h to a cross-piece, I, fastened upon the tub A and at one end of the same. Hinged at r; to this cross-piece is a box-lid consisting, essentially, of sides J J and a top, K, the latter being slotted longitudinally at 70, to permit play of the lever F. Slot 7c is flanked by a pair of stops, L L, for a wedge, key, or pin, M, to bear against, which latter is passed through a transverse slot or perforation, f, of lever F. m is a cord or chain that prevents this key being detached from the lid.

The sides of the lid are grooved or slotted vertically at j j, which grooves are in line with the guides O 0 of the tub, and receive sliding push-pieces N N, that bear upon the journals (1 d of the rubber, as more fully shown in Fig. 4. The upper ends of these push-pieces have lateral extensions n n, to enable any desired pressure to be imparted to the rubber. This result may be accomplished in various ways;

but we prefer the method seen in Fig. 1, where as to be readily uncoupled from the tub before opening the lid. The same illustration shows that a weight, 0, may be used instead of a spring.

S is a leaf or flap hinged to the free end of the lid, which flap can be opened to permit inspection of the clothes or to allow water being poured into the tub.

The operation of our washing-machine is as follows: After the clothes have been placed in the tub and the lid closed, the handle H is grasped and operated so as to impart avibrating motion to the rubber D, the journals of which, (I d, are now confined within the guides 00 of said tub. It is evident the rubber is maintained in this normal or depressed position by the weights or springs, as previously described; but this pressure is not positive or unyielding, as the springs will give suflicientl y to compensate for any unusual thickness of elothing. Vhen the washing is finished and the clothes are to be removed from the tub, the rod G is grasped and the rubber is lifted bodily until its journals (1 d come in contact with the under edges of the lid sides J J, as seen in Fig. 2. This act forces the pushpieees N N up within the groovesjj and brings the slotf' of lever 33 in line with the upper surface of the lid. The key M is then driven into said slot f, thereby temporarily coupling the rubber to the lid and permitting the latter to be instantly swung over to the position seen in Fig. 3, so as to afford the most convenient access to the tub. Vhen the lid is brought to this position the stops L L" support the key M and prevent the lever I! sliding down within the slot k of said lid. After the tub has been refilled with clothes the lid is closed and the wedge or key M is driven out of the slot f.

The journals d d of the rubber then descend directlyinto the guides G G of the tub and the washing is continued in the manner just de- 0 scribed.

'We claim as our inveniion 1. The combination, in awashing-maohine, of tub A, having guides G G, that receive the journals d d of a vibrating rubber D, said 5 rubber being provided with an operating-lever, F, traversing the longitudinal slot 70 of a lid, K, which covers said tub and is hinged thereto at t, the sides of said lid being grooved vertically at j j, and push-pieces N N being 5o inserted in said grooves, the upper ends of said push-pieces being'provided with lateral extensions n n, to which the yielding pressure devices are applied, and the lower ends of said push-pieces being in contact with said journals (1 d, as described.

2. In combination with a washing-machine having a tub, A, provided with guides C G, that receive the journals (:3 d of a vibrating and vertieally-shiftable rubber, D, having a transversely-slotted lever, Ff, playing within the longitudinal slot It of a lid, K, hinged at i to said tub, the fixed stops L L, fastened to said lid and on opposite sides of said slot is, and a key, M, which key is passed through said slot f when said rubber is raised out of said tub, as described.

In testimony whereof we affix our signatures in presence of two witnesses.
